12 Claims.

The present invention relates to improvements in metal working machines and more particularly to automatic chucking machines wherein there is provided a plurality of tooling stations 5 supported by one or more carriers and a plurality of work holding devices supported by a carrier. The tooling sta-tions and workholding stations are so positioned relative to one another that successive pieces of work may be .operated upon by one or more tools.

Machines of' this type have heretofore 'been made with the tooling stations supported on a carrier slidable along horizontal ways provided on a bed or base support, the carrier being moved longitudinally toward and away from the work station. Intermediate of the tool stations and work stations, the bed was provided with a trough into which the chips and cut away metal fell. The cut away metal would rapidly pile into heaps and interfere with the movements of the carriers, necessitating the shutting down of the machine while the metal was removed, often resulting in the loss of iive to ten minutes running timeper hour. Moreover, the small chips would fall or 25. fly onto the horizontal ways, whereupon the carriers would move over same, often doing serious damage to the machine and necessitating a complete shutdown while the carrier was removed and the ways repaired.

An object of the present invention is to provide a machine wherein the foregoing disadvantages are eliminated.

A still further object is a machine wherein the tool carrier is supported on vertically arranged Ways which support and space the carrier above and away from the base of the machine, enabling the trough to be cleaned out while the machine is operating.

A still further object is the provision of a support for the carrier which is arranged to one side of the base and also serves as a support for a second tool carrier which is arranged at right angles to the iirst tool carrier and is adapted to carry tools to 'do outside finishing on the pieces carried on the working stations.

A still further object is a machine of this kind wherein the tool carriers are so positioned that the driving means therefor may be readily interconnected to enable operation of same through a single motor.

A still further object is an improved tool carrier for outside work wherein the carriers are supported within a casing in superposed relationship and slidable on and relative to one another. e

A still further object is a machine of this type which is particularly compact, of relatively simple construction, highly efficient, and economical both to manufacture and operate.

Other objects will be in part obvious and in part pointed out more in detail hereinafter.

The invention accordingly consists in the features of construction, combination of elements, and arrangement of parts which will be exemplied in the construction hereafter set forth and the scope oi the application of which will be indicated in the appended claims.

In the accompanying drawings:

Fig. 7 is a plan view of the base of the machine; and

Fig. 8 is a fragmentary detailed View of one of the supporting ways.

Referring to the drawings, there is provided a base or bed IB having end walls I2 and I4 and a transverse wall I 5 spaced approximately mid way between the end walls; the transverse wall I6 and end wall I 4 being of greater height than the end wall I2. The base is further provided with a forward side wall I8 and a rear side wall 22; that portion of the rear side wall 20 intermediate 'of the end wall I2 .and transverse wall I6 also deiining the inner wall of a rectangular support 22. The high part of the base between the end wall I4 and the intermediate' transverse wall I6 is provided with a ltable top 24 having a pair of spaced horizontally arranged parallel ways 26 positioned adjacent the side walls III)` thereof and adapted to carry a work support, as

will hereinafter be described.

The low part of the base is further provided with a trough 2B defined by the base walls I2, I6, and I8 and the inside wall 20 ofthe vertical support 22. Preferably, the top peripheral edge 32 of the wall I2 and that part of the wall I8 intermediate of wallI2 and wall IIi is somewhat lower than the level of the table top 24. The bottom of the trough 28 may be provided with an opening 3l having any suitable screen therein to permit the oil to flow therethrough onto the bottom 35 of the base from which it may be withdrawn in any suitable manner. The veru tical support 22 is provided with a flat top 34 of substantial width and on the same level as the table top 24.

Supported on the top face 3l! of the support 22 and secured to the support in any suitable manner is an extension member 38 having a side face 40 and a top face 42.

side face 48 and to which is removably secured a horizontally. arranged way 46 having generally the shape of an inverted V and preferably has the shape of an isosceles triangle with its base parallel to the base 42. Disposed below the way 4G and on the side face l0 of the member 38 is a vertically disposed way 48, the way i8 preferably being ap*- proximately on the level of the table top 24 and above the peripheral edge 32 of the base I8.

The support 22 and extension member 38 are adapted to carry a tool carrier 58, which tool carrier is provided with slides 52 and 54 adapted to cooperate with the ways i6 and 48 of the extension member 38. As indicated in 2, the carrier il() has an outwardly extending projection 56 to which the slide 52 is removably secured in any suitable way, such as by bolts 58. As the projection 56 overlies the top face 42 of extension 38, the slide 52, the lower face of which is notched as an inverted V, overlies the way 46. The slide 54 is disposed below the slide 52 and is adapted to engage the way 4B of extension 38 and is pref erably located below the center line of the carrier 58, whereas the slide 52 is located above the center line, thus tending to equally distribute the weight of the carrier 50 relative to the ways.

The carrier 55 is provided with a plurality of tool holders 88 concentric with the center thereof and which are aligned opposite a plurality of work holding chucks 62 carried by a work supporting head G4; there being one less tool holder than the number of work chucks. The work supporting head is provided with slides 6@ adapted to engage the horizontal slides 26 of the table top 24. The vertically disposed ways of the support 22 and the horizontally arranged ways 28 of the table top 24 are so positioned relative to one another that the center of the tool carrier 58 and the center of the work supporting head Gli are in axial alignment, whereupon as the tool carrier is moved longitudinally it will move the tools into and out of engagement with the pieces carried in the work holding chucks.

There is also carried on the top face 34 of the support 22 and positioned intermediate of the chucks 62 and spindles Si! a casing 68 supporting therein a plurality of cross slides 78d, lilb, and Mc; each slide being adapted to carry at its inner end l2 a suitable tool which, as the slides are moved inwardly, will engage and perform an operation on the outside surface of the work piece carried in the aligned work holding chuck.

From the foregoing, it will be seen that as the tools carried by the spindles @il and by the cross slides 'i0 operate upon the pieces carried on the work chucks 62, the metal cut off by the same will drop into the trough 28 of the base and any oil that drops therein will flow through the screen 30 into the base 3G and then be drawn olf. However, as support 22 positions and spaces the carrier G above the trough 28, it is possible without stopping the machine to remove the metal therefrom by drawing it out over the peripheral edge The top face 42 of the member 38 is provided with a key 44 adjacent the,

32 which extends from the forward and outer edge of the wall I6 around to the support 22. If desired, a conveyor could be placed beneath the carrier 50 to receive the cut metal and continuously deposit it over the top edge of the end wall l2 into a suitable receptacle. Inasmuch as the top way 46 is spaced considerably above the center of the carrier and work head, there is little danger of flying chips landing thereon, and even if they did, due to the inverted V shape of the way,

'they would readily slide off. As indicated, both the way 46 and slide 52 are removably secured in place. Thus if undue wear occurs, it will be possible to re-adjust the carrier into alignment by shimzning behind the slide 52 or, if necessary, renewing these parts.

The longitudinal movement of the tool carrier 50 to carry the tool spindles into and out of engagement with the work pieces is accomplished by suitable connections to a motor 14. The motor 14 connects through a suitable reduction gear and bevel gear '16 to a short shaft 'I1 in the casing '!8, which shaft l1 in turn drives a ver tically arranged shaft 88 through suitable bevel gears 19. Shaft 80, through meshing bevel gears 8l, drives the horizontally arranged shaft 82, which shaft, through meshing gears 83 and driven gear 84, drives a shaft 85. Shaft 85 is provided with a worm 88 adapted to engage a gear 87 mounted on a shaft 88, on which shaft there is also mounted a cam 89 adapted to engage a follower 90.

The casing '18, shaft 82, and follower 98 are all supported in fixed position on support 22, whereas the gears 83, 84, and shaft 85, gear 8l, shaft 88, and cam 89 are all supported on and movable with tool carrier 58; the gear 83 being keyed to the shaft 82 to rotate therewith as it moves longitudinally along same. Thus upon rotation of the motor 'I4 the cam 89 will be rotated to move the tool carrier 5B longitudinally along the ways 46 and 48 into and out of operative position.

Means are also provided to index the chucks to successive stations and rotate the chuck at each successive station. These means may be the same as those fully described and set forth in the patent to Spring No. 2,053,748, and as they form no part of the invention they need not be further described herein.

The motor 14 is also adapted, through suitable connections, to cause movement of the cross slides 1l) transversely in the casing 68 to carry the tools carried thereby into and out of operative position relative to the chucks 62. As may be seen from Fig. 5, the casing 68 is provided with a division wall 69 between which there is located the cross slides 10. The cross slides are of substantial length, width, and depth and of considerable weight, being made generally of a one-piece bar with a recess 92 therein in which there is positioned a block 94 from which a cam follower 95 projects. The cam follower extends through a suitable opening in the division wall 69 of the casing 68 to engage a cam 96 which is provided with a groove 98 in which the cam follower 95 rides.

The block 94 is somewhat shorter than recess 92 to permit adjustment of the cross slides 18 relative to the cam follower 95. The adjustment is made through a pair ofset screws; one set screw I 80 being screw-threadedly mounted in the end of the cross slides 10 and having its inner end contacting with the block 94, Whereas the other set screw 682 projects through an opening 1n the end of the cross slide 'lll and is screwthreadedly connected to the blockv 94. Thus by backing of the screw Ulli and then adjusting screw |02, the blockv may be moved longitudinally within the cross slides 1B to adjust the cam follower 95, and when properly adjusted screw lllll may be screwed into abutment with the end of the block 94 to maintain same positioned. The cross slides are vertically supported one above the other;` the lowermost slide 'ma resting on the bottom 'H of the casing, the 'second or middle slide 1th resting on the top face of the slide 10a, and the uppermost or top slide 'ille resting on the top face of the slide 10b. Thus as the slides are moved into and out of position they ride relative to one another and serve to maintain one another in substantially perfect alignment. Moreover, as the weight of the slides is so greatly in excess of the weight of the tool, the tool will be maintained in perfect alignment relative to the working piece.

Each cam 96 is key mounted on a shaft 91; the shaft having one end mounted in a bearing 99 carried in the casing t8 and the other end in an adjusting member lill rotatably mounted in the casing 68 and keyed to the shaft 91. Intermediate of the adjusting member IGI and the cam 96 is a gear H33 loosely mounted on shaft 91 but adapted tobe secured to the adjusting member lill. The gears m3 each mesh with worms |05 carried on the shaft |07 mounted in the bearings in the casing 68, The-shaft lill is rotatably connected through bevel gears H39 to a shaft Ill), which shaft connects through suitable gears lll to the shaft Sll which is rotatably driven, as heretofore explained, by the motor 74. Thus it will be seen that the longitudinal movements of the cross slides 'ill are in timed relation to one another.

In order that the position of the cross slides 'Ill may be adjusted relative to one another, the adjusting member l0! is provided with a plurality of openings Il2therethrough and the gear l03 is also provided with a plurality of threaded openings H3 therein; the number of the openings in the one member being one or two less than the number of openings in the other member. There is also provided a locking bolt H4 extending through the adjusting member lill and screw-threadedly engaging thev gear |03. Thus if it is desired to adjust the cams, it is possible by removing bolt H4 from gear H33 to rotate the adjusting member im, which, like cam 96, is geared to shaft 91, until one opening lin the adjustment member is aligned with one of the openings in the gear, whereupon screw H4 would be re-inserted and the cam locked to the shaft at that position. Thus it is possible to adjust the cams relative to the cam followers independently of one another and thereby adjust the relative movements of the cross slides relative to one another. It will thus be seen that when the motor 'M rotatesthe shaft H31 will also rotate to rotate the cams 96 which in turn will cause reciprocal longitudinal movement of the cam followers 95 to cause the cross slides to be moved into and out of position relative to the chucks. The adjustment of the cams may be such that one may be moved into position as the other moves out. Thus it is possible to adjust the cross slides 'lli relative to the block 94 to change the positioning of the tool and, by adjusting the cam relative to the follower, to adjust the transverse movements of the cams relative to one another.

The operation of the machine will be readily understood. Assuming that the chucks are indexed at one station and rotating at said station, the tool'carrier 5D'wil1 bring the spindles and tool carrier therein intofengagement with the pieces carried in the chuck, and simultaneously and in timed relation thereto the motor will cause 'the cross slides to move transversely to perform operations on the outside surface of the piece being worked. When thel work has been performed for a predetermined period of time, the tools will be withdrawn vfrom the pieces-being worked and the tool carriers and tool cross slides will move out of position relative to the pieces being worked. v

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. Y
